Hi,
I decide to use Corona for a production render. It is for a contract, so the time line we had for preparing the scene is very very short!! so please don't consider the details. I try this version of the image with low external light (from planes with Corona portal material, one for each window) and I've adjusted a little the contrast in post. I find the light distribution very cool!
Btw, the scene has about 12M polygons and it take 8h30' for 500 passes, using a I7 980 3.33GHz.
